The equivalent expression of 25 - 64 are "a), b) and c)"
The given expression is:
25 - 64
To find, the equivalent expressions are:
a) 25 + 40x - 40x - 64
= 25 - 64, is the equivalent expression.
b) 25 + 13x - 13x - 64
= 25 - 64, is the equivalent expression.
c) (5 + 8)(5 - 8)
Using the algebraic identity,
(a + b)(a - b) =
=
= 25 - 64, is the equivalent expression.
d) ( + 13)( - 13)
Using the algebraic identity,
(a + b)(a - b) =
=
= - 169, is not a equivalent expression.
e)
Using the algebraic identity,
, is not a equivalent expression.
∴ The equivalent expression of 25 - 64 are "a), b) and c)".

The difference between the diameters of the two planets is
<h3>How to write in scientific notation</h3>
Given:
- Saturn = 1.21 x 10^5 kilometers
- Neptune = 4.95 x 10^4 kilometers
Difference in diameters in scientific notation = (4.95 x 10^4) - (1.21 x 10^5) +
= (4.95 - 1.21) × 10^(4 - 5)
= 3.74 × 10^-1
=

Given:
Triangle ABC has been rotated 90° to create triangle DEF.
To find:
The equation, in slope-intercept form, of the side of triangle ABC that is perpendicular to segment EF.
Solution:
It is given that triangle ABC has been rotated 90° to create triangle DEF. It means the angle on the intersection of lines BC and EF is 90 degrees.
So, the line BC is perpendicular to segment EF.
The line BC passes through the points B(4,5) and C(1,2). So, the equation of the line BC is:
On further simplification, we get
Therefore, the required equation is .

Answer:
- Arithmetic
- common difference = 7
Step-by-step explanation:
First differences are ...
-38 -(-45) = 7
-31 -(-38) = 7
-24 -(-31) = 7
The first differences are constant, so this is an arithmetic sequence with a common difference of 7.
